A hurricane becomes more powerful by evaporating water from oceans
Answer:
D. Upward force on the shuttle
Explanation:
The hot gas from space shuttles released downward causes an upward force on the shuttle and propels it up the more.
- This hot gas is produced from super cooled oxygen and hydrogen tanks within the shuttle.
- The upward force on the shuttle allows the craft to escape the gravitational pull of the earth on the shuttle
- Special level of rapid acceleration must be attained for the shuttle to escape the earth pull.
Answer:
The kinetic energy K of a moving object is: K= 1/2mv to the second power
where m is the mass and v the velocity of the object.
Using this formula, we can calculate v for this problem
Explanation:
Answer:
129.2 C
0.33758239177 mm
Explanation:
n = Number density = 
i = Current = 170 A
t = Time taken = 0.76 s
d = Diameter = 6 mm
Charge is given by
The charge passing throught the motor is 129.2 C
Current density
Drift velocity is given by
Distance traveled
The electron traveled 0.33758239177 mm
